摘要
通过对屯兰矿煤层顶板岩性的研究,摸索出符合屯兰矿实际情况、经济、合理的注浆加固技术。通过对破碎顶板采用注浆加固,增强了破碎顶板的整体性及强度,有效地控制了顶板下沉,避免了巷道二次维护工程,为井下职工创造了安全环境,保证了矿井的安全生产。
Through study of Tunlan coal mine roof lithology, explores in line with the actual situation in Tunlan coal mine, economic and reasonable grouting reinforcement technology. Through grouting reinforcement the broken roof, increase the integrity and strength of broken roof, controls the sinking of the roof effectively, avoids the secondary roadway maintenance engineering. Creates a safe environment for mine worker, ensures safety production in mine.
